TheStreet Ratings team rates CALAMP CORP as a Buy with a ratings score of B. TheStreet Ratings Team has this to say about their recommendation:
"We rate CALAMP CORP (CAMP) a BUY. This is driven by multiple strengths, which we believe should have a greater impact than any weaknesses, and should give investors a better performance opportunity than most stocks we cover. The company's strengths can be seen in multiple areas, such as its robust revenue growth, largely solid financial position with reasonable debt levels by most measures, solid stock price performance, good cash flow from operations and increase in net income. We feel these strengths outweigh the fact that the company shows low profit margins."
